BUY PRINT July 1942. Back at the Melrose Park Buick plant near Chicago. "Production of aircraft engines. Reconditioning used spark plugs for use in testing airplane motors, Mighnon Gunn operates this small testing machine with speed and precision although she was new to the job two months ago. A former domestic worker, this young woman is now a willing and efficient war worker, one of many women who are relieving labor shortages in war industries throughout the country."
